The Dolores Park Movie Night happens once a month or so, or whenever someone has it together to do it, so far, the 2nd Thursday of every month during the non-rainy season. It's been running for a few years. A group of people set up to show free movies on a big outdoor screen in the park. Bring a blanket and set up early with a picnic! Dogs are allowed. There is sometimes a popcorn stand or drinks for sale from vendors or the organizers. The Tamale Lady may also be in the area.
